I bought myself a Bose SoundLink Max as a Christmas present to myself. I'm listening to the PodCasts you linked to as I type this. Very interesting & informative.
I'm a big fan of math. While the 6.5 CM might be the target of a lot of "man-bun" derision, the quantifiable numbers seem to indicate that the animal would have a different opinion of the viability of this cartridge if it gets shot by one. As long as it is used appropriately (it isn't a magical chambering), it can definitely be a good choice. Wide spread availability is a plus.
For reasons I can't explain, I've always had a bias against the Weatherby chamberings. But while researching this particular category, the numerous superlatives about the .257 Wby gave me pause & made me think that I might need to take a closer look at this particular chambering. It seemed like a good solution to a lot of my anticipated scenarios. I was curious how often it would get recommended & at this point in the thread, I think it's in the lead by a significant margin.
I passed on a 270 Win in a LH Sako 85 Bavarian at an attractive price because I thought it was too close & redundant to my LH Sako 85 Hunter in 30-06. Ever since then, I look back & think I may have made a mistake. It might have been a really good option to fill a slot in my safe. Doh!
Nice left-handed Ruger M77's with 24" barrels will appear on rare intervals. I've come close to buying a couple of them. I've seen a couple of LH Sako's but I wish their barrels were a bit longer than 22" for this particular cartridge. Maybe that shouldn't be a concern.
Thanks for all of the informed feedback! For me, no decision is complete until I overthink it & have way too much info.
